Try to find this address in hotspots when adding a spot. Even when I pin manually in the right locations it gives me a different address. See if this can be fixed. Maybe it has to do with google maps now finding addresses differently than before and its not updated in HS, just a thought..
You can manually enter the address and place the pin. Just set the option for sticky pin to false, then you can manipulate the address and pin as you want.
Now about the address - I have no idea why it happens, but if the reverse geocoder gives us something else, then I can't do something. As far as I'm aware what google uses for their own google maps differs slightly from the public apis that we are given. So some different results are possible.
I did sticky - false and all that. Just wanted you to take a look at this specific address, usually everything is ok, but this strangely does not work.
Maybe there is something about it that you can spot as the developer...
